YAppnea'azm mea January 4,-{19'29Qse`ria1 f Y This invention isan improvement in beam protectors, and moreparticnlarly inprotectors'for thepbeamsof railroad'bridges.-

Bridge beams ofthe character inV question .5 deteriorate veryrapidly,due"to the actionof the blast discharged by locomotives passing `beneath the beams .The action of the sulphur products discharged by the locomotives inV connection with the moisture in the atmos' 39 phere, tend to erode and weaken the beams.

One of the primary'objects of the present invention is the provision of'a type of protector, which provides .complete protection for.

theexposed partsof the'beam'. I s

Another object is theprovision of azprotector'rcapable of beingeasily applied to beams in existingstructures, and Awhich'V is easily removed when desired for any purpose.` Another object is thelprovision of a pro-.s4

tector` with which may be combined protecting means for all of the exposed surfaces vof the beam, held infplace bythe protector .V'properf i Y Another-object is the provision of'atype of protector so constructed `that it may be applied to beams of any length. Y

. `With these and other objectsin View invention consists in the construction andy o novel combination lot Aparts VVfully describedv 0 hereinafter, illustrated inthe accompanying drawings, and'pointed ontfin the claimsappendedhereto, itbeing Vunderstoodthat various changes inv the form, proportion, size `and minor-*details of constrnction within the scope of the'claims, may beresorted to with-` out departing from the spirit of the-'invention.AV '.5 In the drawings forming apart h-ereof:-jl Fig. 1 is a transverse .vertical section of a Y beam provided with the improved protector.

After theY protectorzhas been placedlas l above described, blocks'iof wood orthelike, are dropped dow'nf between the l `side plates 3v and vthe? beam flange edges, sas"sshowninjv Figs. 1, Q' and 3. f 'These `blocks :are of an thickness. to, fill thel spacebetween-the reedges,
